New CDL-hosted Databases Available from the Web (at [http://www.dbs.cdlib.org/])

July 13, 1999 Author: CDLCategories:

a. English Short Title Catalog (ESTC)

The database contains over 423,000 citations and is updated daily. It includes information on works printed in England and its dependencies from 1473 to 1800, as well as works printed in English anywhere else in the world during that period. There are selected titles in other languages, including French, German, and Latin. Subject headings are included for works published in 1700 or earlier. ESTC is produced by the British Library and ESTC/North America.

We have tried to be consistent in providing the same search options offered in the Telnet version of ESTC. Note that although Date, Language, and Publication Type appear as Optional Limits on the Power Search screen, they may also be searched independently, just as they are in the Telnet version. They are presented as Optional Limits to be consistent with other CDL-hosted web databases.

b. GeoRef

The GeoRef (@Stanford) database is produced by the American Geological Institute, and indexes and abstracts the worldwide literature on geology, including information on energy sources, volcanic eruptions, earthquakes, groundwater pollution, nuclear reactor sites, landslides, and erosion, as well as the history of the earth, the structure of the earth, the study of ore deposits, and geostatistics.

GeoRef selects articles and documents from over 3,500 journals and serials in more than 40 languages, as well as maps, theses and dissertations, conference papers, government publications, books and book chapters, and reports. Coverage is worldwide in scope. About 40% of the publications come from the United States. A portion of the references are received, in exchange, from Bureau de Recherches Geologiques et Minieres (BRGM), the Institut de l’Information Scientifique et Technique (INIST), the Czech Geological Survey (Prague), Geological Survey of Canada (GSC), and the Bundesanstalt fur Geowissenschaften und Rohstoffe(BGR).

Citations cover the years 1785-present for geology of North America and the years 1933-present for geology of other areas. The Stanford file includes the entire GeoRef file of 2.1 million records (as of 2/99) and is updated monthly. Approximately 60,000 records are added yearly.
